Start small, stack more later
One power module (BDC 95045-A1) plus 2.56 kWh battery modules stacked 2 to 10 — so the same battery grows from 5.12 kWh to 25.6 kWh as your usage grows. No need to buy the biggest size on day one.
Safe, cobalt-free chemistry
Cobalt-free lithium iron phosphate (LFP) cells, IP65 rated for indoor or outdoor installation, wall-mounted or floor-standing. Certified to IEC 62619, CE, CEC, RCM and UN 38.3.
Built for Growatt hybrid homes
Designed for Growatt MIN-XH and MOD-XH hybrid inverters. A practical retrofit for homes that already have a compatible Growatt inverter, with remote firmware updates.
Monitored, not guesswork
CAN/RS485 communication, with state of charge, system voltage, current, cell voltage and cell temperature monitored. Remote firmware upgrade is listed on the datasheet.

Questions
Growatt ARK XH FAQs
Have questions about the Growatt ARK XH? Our solar specialists are available to help call 1300 646 419.
The Growatt ARK XH comes with a 10-year warranty. The warranty is given in the January 2024 ARK XH datasheet. The battery itself uses cobalt-free LFP chemistry with IP65 protection, and it is certified to IEC 62619, CEC, RCM and UN 38.3.
It pairs with Growatt MIN-XH and MOD-XH hybrid inverters. MIN-XH covers single-phase homes, taking 2 to 7 battery modules, while MOD-XH covers three-phase homes, taking 3 to 10 modules. If your inverter is a different brand or a non-hybrid Growatt model, ask us to check compatibility before quoting.
Each stack holds from 5.12 to 25.6 kWh, built from 2.56 kWh modules. You can start with as few as 2 modules and add more later, up to 10 modules per stack, as your household’s needs grow.
Yes. It uses cobalt-free LFP chemistry, carries IP65 protection, and meets IEC 62619, CEC, RCM and UN 38.3 standards. It also comes with a 10-year warranty.
The ARK XH tracks its charge level, voltage, current and cell health over CAN/RS485. It pairs with Growatt MIN-XH and MOD-XH hybrid inverters, so performance is monitored, not guessed.
